i Be it known that I, FnAivi the followinglis aspecication. ,y I Y lldyinvention relates to certainimprove ments in padlocks for which a patent was` granted to me onthe Aeighth dayof June, 1915, No. 1,142,638. g- Oneobject of my inventionis to improve of the lock and at the same time lengages the heel of the, shackle, when thefshackler is closed. l

A further i obj ectV ofthe invention is to.A dispense with the tubular pivot for the lever and to provide means whereby the lever can pivot-,- allow ing clearance of the spring; U

In the raccompanying drawings: Y

My invention relates particularly to improvements in padlocks and ^they-designl 'of thecasing may vary without departingfrorn the essential vfeatures of the invention.

This boltis notched at 8 and 97and isv arl rangedto slide on'the' pins-Hyland11pro-v I jeotingrom the casing I. A `spring 12, Fig. 7, is vmounted on thepin lQand one a-rm V13 efthis spring extends backfofa lug 14 on "the bolt, while the other end lgrests on a flever. 117 pivot-ed at`18 to ay pin projecting Vfrom .thezcasing .This spring not only tendsH to` throw the bolt, but l also tends to raise the `lever into the positidn'illustratedl inFig. 1

i A18. The lever also" has.v a portion 21 bent in the.g opposite direction from the portion 20, whichi'sl arranged tofengagethe heel 22 of the shackle when'gthe shackle is in thefclosed' nposition'fas `shown .in'Fig Vl2', lso that Whiley jthefnoseof the'shackle is held by theportion .27 ot'thefbolt, the heel ``oflthe vshackle is held bythe projection 2l of the'lever, making fwhatis termed a double L lock.'l .A coiledspring23is hookedontothe pro-` Y jectio'nl of the` lever and onto? ak pin 2lat the heel of the shackle. f This spring -moves thel shackleto its open position', asfshown' in `Fig-.1, when the shackleiis releasedby the bolt` and also places V`tension on the` lever when the shackle is in-the closedA position,

tending to hold the projection 2170i the lever contact with the heel of the shackle.

Inorder to lock 'the lever, whenfits pro-A 'Y fjectionf21 bears against the heel22ol:l the shackle, I provide-a Y projection 30 on the bolt, which Vrestsl under the projection 21 lof the lever, holding itin such position that 'it cannot be released' without turning the key and withdrawing the bolt. --Themoment tliefgbolt is withdrawn, -thelever is free:k toV A .,105

turn .on its-pivot. y j

25 is the fence ofthe bolt adapted to enter the notches 126-in the tumblers 27., which are mounted on the pin 11 andhave springs -28 bearing against the pin 29. ,It will be understood that the number of notchesl in the tumblers may be varied and the shape of the tum'blers may also be varied, if desired. Notches may 'also be provided in the tumblers for a master key.

31 is a key hub adapted to receive a key. The pins 3, 10, 11, 29 and 32 project from one section of the easing and through openings in the other section and are, riveted so as to hold the two sections firmly together. Several of these pins also act as pivotsfor the mechanism. f Y

It will be seen on referring to Fig. 2, that when the shackle is closed the portion 7 of the bolt 6 enters the nose of the shackle, while the portion 21 of the lever rests against the heel of the shackle sok that the shackle is doubly locked. By making the lever in the manner shown in Fig. 5, I can Y use a very short pivot pin 18 Vand can hold the lever from twisting by the projecting portions 16, 19 and 20. By making the short -pivot pin 18, I allow sufficient room Jfor the spring 23 so that it has a direct pull when the shackle is moved from the open to the closed position,'and vice versa.

I claim:

1. The combination in a padlock, of a casing; a shackle pivotally mounted in the casing; a bolt arranged to engage the nose of the shackle; a lever pivoted to the casing and having an arm located in the path of the `nose and of a shape to close the opening'V in the casing when the shackle is raised, said lever having another arm arranged to engage the'heel end of the shackle, thebolt, when in the locked position, also engaging the lever and preventing Vits withdrawal from the heel of the shackle; a short pivot pin for the'lever; anda spring attached to a projection on the lever and to the heel of the shackle.

2. The combination in a padlock, of a casing; ashackle pivoted thereto and notched at its nose end; a sliding bolt mountled in the casing and having a portion arranged to enter the notch in the nose end of the shackle; a pivoted lever having a projection at the rear arranged to engage the heel end of the shackle, when the shackle is closed, and having a portion arranged to close the opening for the nose end of the shackle, when the shackle is in the open position, and also having projections of substantially the same height so as to bear against the casing; a short pivot pin, for the bolt; and a spring extending from one lof the projections of the lever to the heel of the shackle, said spring extending over the pivot pin.

3. The combination in a padlock, of a casing; a shackle pivotally mounted in the casing; said shackle having a notched nose end; a sliding bolt mounted in the casing and having a projecting portion arranged to enter the notch in the shackle; two pins on which the bolt slides; a coiled spring mounted on one of said pins, one end of said spring bearing against the bolt and tending to move it forward; a lever pivoted to the casing and having a projecting portion against which the other element of the spring rests; and a coiled spring extending from said projection to the heel of the shackle, the lever having a plate portion which closes the shackle opening when the shackle is raised.

4. The combination in a padlock, of a casing; a shackle pivotally mounted in the casing; a bolt arranged to engage the nose of the shackle, said bolt having a projecting lug at its forward end; pins on the casing for engaging the bolt; a lever pivoted to the casing and having an arm located in the path of the nose of the shackle and of a shape to close the opening in the casing' when the shackle is raised, said lever having another arm arranged to engage the heel of the shackle; a spring mounted on one of the guide pins of the bolt, one arm of the spring engaging the lug on the forward end of the bolt, the other arm of the spring engaging the lever; and a spring extending from the lever to the heel of the shackle.

In witness whereof I aiiX my signature.
